Protein Construction

A DNA sequence encoding the human NRG1 isoform alpha (Q02297-1) extracellular domain (Ser 20-Lys 241) was fused with a polyhistidine tag at the C-terminus.

Accession#

Q02297-1

Expressed Host

HEK293 Cells

Molecule Mass

The secreted recombinant human NRG1 consists of 233 amino acids and has a calculated molecular mass of 25.5kDa. In SDS-PAGE under reducing conditions, the apparent molecular mass of rh NRG1 is approximately 40-45 kDa due to glycosylation.

Formulation

Lyophilized from sterile PBS, pH 7.4Please contact us for any concerns or special requirements. Normally 5 % - 8 % trehalose, mannitol and 0.01% Tween80 are added as protectants before lyophilization.

Shipping

In general, recombinant proteins are provided as lyophilized powder which are shipped at ambient temperature.Bulk packages of recombinant proteins are provided as frozen liquid. They are shipped out with blue ice unless customers require otherwise.

Stability & Storage

Samples are stable for up to twelve months from date of receipt at -20℃ to -80℃. Store it under sterile conditions at -20℃ to -80℃. It is recommended that the protein be aliquoted for optimal storage. Avoid repeated freeze-thaw cycles.

Reconstitution

A hardcopy of datasheet with reconstitution instructions is sent along with the products. Please refer to it for detailed information.
